Buonconsiglio Castle was originated from a fortified building was erected in the 13th century next to the city's walls. This first building was called Castelvecchio ('Old Castle'), and was the seat of the Bishopric of Trent from the 13th century onwards to the end of the 18th century. The castle is composed of a series of buildings of different eras, enclosed by a circle of walls in a slightly elevated position above the town.
The Castelvecchio is the oldest and most dominant building of the entire housing development. The Magno Palazzo is the 16th expansion in the forms of the Italian Renaissance, wanted by the Prince Bishop and Cardinal Bernardo Clesio (1485-1539), the third part, in the southern end of the complex is the known Eagle tower, which preserves the famous Cycle of the Months, one of the most fascinating pictorial cycles of profane the late Middle Ages.
Bishop George of Liechtenstein was the first to enlarge the castle, in the late 14th century, turning it into a well-styled residence. The Castelvecchio was further modified by Johannes Hinderbach, who had the double loggiato and the Gothic entrance gate built. In the first decades of the 16th century, Bishop Bernardo Clesio had a new residence, called Palazzo Magno ('Grand Palace') built in Renaissance style alongside the old castle. The last great addition was the so-called Giunta Albertiana, from the name of Bishop Francesco Alberti Poja (1686), with which the Castelvecchio and the Palazzo Magno were united.
The castle remained the seat of the Prince-Bishops until 1803. Used by the Austrians as military barracks and, later, as a jail, it decayed. In the 1920s, when Trento was returned to Italy, it became seat of a National Museum and was restored. Since 1992 it is home to the Provincial Gallery of Art.
According to legend, it was connected by a secret tunnel to the city's cathedral, which allowed the prince-bishops to move unseen between them.
References:Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
